This study mainly investigates the behavior of hollow piles and composite piles through experiments and numerical analysis. The results from experiments and numerical analysis indicate that increasing the length-to-diameter ratio can improve the load carrying capacity of piles and reduce settlement.
Composite piles are widely used in geotechnical field for its mechanical and physical properties. Composite piles are usually filled with concrete. Although the use of composite pile is increasing, the proper design and its ultimate load carrying capacity are still under investigation. This research mainly aimed to study the behaviour of hollow pile and composite pile. Two types of model pile were prepared which are hollow pile and composite pile. The composite pile was made up of stainless steel. It was hol-low steel pipe has outer and inner diameters of 13 mm and 10 mm respectively, filled with standard mor-tar. The pipe without filling mortar known as hollow pile. Different length-to diameter ratios of 10, 15, 20, 25 and 30 are considered by varying the pile length to simulate behaviour of stiff piles. Experiments were conducted on both hollow pile and composite pile embedded in layered soil under static axial load and static lateral load. Experiments results were validated with the results obtained from finite element soft-ware (ABAQUS). The experimental investigations and numerical analysis results indicated that increasing the L/d ratios increases the load carrying capacity and decreases the settlement in both the piles.
